In Lafreniere, the Maple Leafs would get a rising star that scored career highs in goals and points a season ago, but given their desire to chase a Stanley Cup right now, it doesn't make too much sense. For the Rangers however, this would be a fantastic pickup, as he would add more firepower to an already lethal lineup, and would help them get younger on the blue line too with the departure of Jacob Trouba and the incoming Timothy Liljegren.
Player for player, the value of this deal isn't too far off, but both teams are looking to win now, so this one likely won't come true, but with the Maple Leafs not wanting to lose Mitch Marner for nothing in free agency, this wouldn't be the worst idea for a trade.
